Hi binhsuper,

This error appears then you attempt to run the editor? Instead of running it, please use the drop-down and select “Verify”. Post the results

If this does not display anything, follow the steps here to generate your Debug Logs. Post them here, along with your Dxdiag/system specs.

Hi binhsuper,

We haven’t heard back from you in a few days, so we are marking this post as Resolved for tracking purposes. If you’re still experiencing this issue, please try the suggestion that I mentioned above then post back here with the requested info.

For anyone else still having this issue and finds this post like I did and then had to go and search for hours more:

You need to install this:
2015 Visual C++ Redistributable

If the install fails like it did with me, you most likely need to install this windows update:
Update for Universal C Runtime in Windows

If that fails then you have to install a couple of other updates first, but first see if the above works. If not, comment and I will post full list of updates needed that I had to go through just to get the c++ Redistributable to install.

thank you thanking thank
